The Common Call Control enabler consists of the following pre-built functional building blocks:

 

• Rule Based Call Routing

Here users can influence the destination of a call by specifying complex routing rules. These rules are evaluated during the setup of the call. Based on these rules, a decision is made about the final destination of the call. The routing rule options can be the followings:

• Time of Day routing
• Day of Week routing
• Day of Year routing (including the management of holidays)
• Calling number based routing

• Rule Based Call Filtering

Special filtering rules can be defined for a number that specifies how to contact numbers at specific times. The filtering rule options can be the followings:

• Time of Day filtering

• Day of Week filtering

• Day of Year filtering (including the management of holidays)

• Calling number based filtering

 

• Conference Call

Conference Call feature enables scheduling of conference calls among different parties. The parties can call into the scheduled call or the system can call back the parties automatically when the conference call is started.

 

• Click-to-Dial (Web Initiated Call)

A multi-party call can be set up by invoking a web service or by clicking on a web widget.

 

• Media Resource Functions Management

Common announcement and common DTMF code handling.

 

• Prepaid Logic

Online charging system integration based on Diameter Sh or legacy protocols.

 

• Account Code, Authorization Code Management

The operator can set an authorization code for connecting calls. For example, the service asks the caller to provide the right code and if the user gives the proper authorization code via DTMF the call can be initiated.

 

• Call Hunting

This feature attempts calls to a predefined list of alternate numbers when the called party is busy. The application tries each number in sequence until a number answers or all numbers are busy in the list.

 

• Provisioning Web Services

Common Call Control enablers require the persistent storage of configuration data (e.g. routing rules). The provisioning of this type of data is done through standardized web service technology to easily integrate with company’s existing BSS or SOA infrastructure.

 

• Self-service Provisioning GUI

The configuration of the different telecommunications services (like routing rule management) can be done with a web based self-service GUI. The user of this self-service GUI can administrate all of the functions mentioned here. In addition to that it can also delegate the
administration rights to other users.

 

• Online Charging Integration

Common Call Control enabler supports prepaid services and can be integrated with online charging systems via diameter (Ro interface) or a custom developed solution.
